To all whom it may concern:

Be it known that I, THOMAS F. McDonooon, Jr., a citizen of the United States, and a resident of Glen Cove, Nassau county, New

, York, have invented a new and useful Improvement in Fly-Traps, of which the following is a full, clear, and exact description.

My invention relates to improvements in fly traps and the object of my inventionis to produce a very simple and inexpensive.

ing drawings forming a part of this specification, in which similar reference characters indicate corresponding parts in all the I views.

Figure 1 is a perspective View of the complete trap, and Fig. 2 is a cross section of the same.

The structure is provided with a base 10 which is preferably flat and can be. conveniently made of wood, though of course other materials can be used, this base having spaced apart and rising from the upper side thereof two uprights 11 which are preferably of an A shape, although they can be given any desired outline. The trap properhas two ends 12 which on their lower ed es are cut away as shown at 13 so as to set over the uprights 11 and fit snugly thereon, the side portions of the end bottomspreferably resting upon the base 10 so as to give to the trap more stability. It will be readily seen that the ends should be cut away at 13 to fit the uprights 11. and that these may be given any desired shape, though that shown is preferable. The end portions 12 of the trap form the ends of the skeleton framework having rails 14: at the top corners con 56 meeting the two ends 12, while near the bottom and on opposite sides are the lower rails 15 which are likewise secured to the ends, and these are raised a little from the base 10 so as to form passa,g eways 16 extending the full length of the trap, these passageways occurring between the baselO Application filed October 30,1916. Serial u near and the members 15' as shown clearly Fig.2.

Th sides, top and bottom ofthe trap are Specification of Letters iatent. v Patelttflfl 11MB 5, ilgii covered with screening 17 and the screening is secured to the, inner walls of the cutaway part 13 of the ends 12, thus forming an A shaped chamber 17' extending longitudinally of the trap and having at its apex numerous openings 18 through which the flies may pass. The screen material around the holes 18 is out so as to have some oiizthe-v around the holes. This, while simple, is 1111- portant, because if it. were not for these prongs 19, the flies might pass backward out of the trap; but with the prongs the will not attempt to crawl back as the prongs g terfere with the outward passage Qfthe res.v

As least one, end of the trap provided wire members 19 of the screen stick upward.

with a door 20 of any suitable kind, covering an opening through the trap end, endangers the flies have collected in the trap'they will I die in a shorttime, or can he k lled as by drowning, and then emptied through the door.

A suitable catohis preferably used to fasten the top part of the trap to the base, and

a convenient way is to provide hasps 21011. the trap ends which engage staples 22.011 the uprightsll as shown in the drawings. The screening 17 of the trap can be applied in any convenient way, and I have shown it".

fastened in place by beading 17 which overlaps the screening and is tasked to the trap ends and rails, but obviously any other suit able means can be employed. When the trap is to be used, some sort of bait attractive to flies is placed on the base 10 beneath the chamber 17. The flies attracted by the bait enter through the passageway .16, and after, eating; the balt wiil naturally fly upward against the. walls of the chamber 17 and will. crawl upward alongthese walls toward the higher and lighter part of the trap. finally passing through the holes 18. through which they will not return because of the interference of the prongs 19, and even if the prongs were. not used, most of the flies would still rema n I in the trap. When a sufiicient number of flies have been caught, the topof the trap 15 lifted from the base and the fiiesci n be emptied as already described.

From theforegoing description it will be K'k-san e seen that by having the base provided with uprights which serve to support and guide the body portion of the trap, and by having this body portion separable from the base, a very convenient and simple structure is made and a trap provided which can be easily set, conveniently moved about, and readily' emptied.

l. A fly trap com n'ising a flat base which serves as a feed board, triangular uprights spaced apart and rigidly secured to the base.

at removable member having closed ends provided with ways shaped to lit over the aforesaid triangular uprights and with the parts of the ends at the sides of the up- -.rights shaped to rest upon the base. said removable meinber having its sides and top screen covered, and a screen covered triangular upwardly extending member in the bottom having a fly opening at the apex,

and one of the ends of the said member having an opening theretlnrough and a door covering the opemn rights spaced apart and rigidly supported thereon, and second aremovable screen covered chamber having its ends closed and shaped to fit over the aforesaid uprights and its side portions spaced apart from the base, the said second member having, oppositely inclined inwardly extending bottom portions with a slot through the apex thereof.

3 A fly trap comprising two separable members, first. a base portion having triangularvend portions spaced apart and rigidly attached thereto, and second a removable screen covered chamber portion having its ends provided with rigid ways shaped to [it over the triangular members and with its sides spaced apart from the base to provide.passageways between the sides and the base, and screen covered up\r\'ardly extendin; oppositely inclined bottom portions having an ingress slot at the apex lhereol,
